91743872 divided by 139 
The aim is to understand the frequency of 139 in 91743872.

Going ahead to step 1:
139 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 139

Step 2:
When dividing 91 by 139, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 139

Let's proceed to step 3:
139 can be fit into 917 6 times, resulting in a remainder of 83.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 834 away from 917, we end up with 83.
Fetch the next digit (4) from the dividend, attach it to 83 and continue: 834 / 139

On to step 4:
If we divide 834 by 139, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 834 from 834 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 139

On to step 5:
The number 139 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 660.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 139

On to step 6:
If we divide 38 by 139, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 6600.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 139

Let's proceed to step 7:
When dividing 387 by 139, we get 2 with a remainder of 109.
Use 2 as the next digit of our solution. 
Result so far: 66002.0
Deduct 278 from 387 and we're left with 109.
Append the next digit (2) from the dividend to 109 and continue with: 1092 / 139

Moving on to step 8:
If we divide 1092 by 139, we get 7 and a remainder of 119.
Use 7 as the next digit of our solution. 
Result so far: 660027.0
Subtract 973 from 1092 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 9:
When dividing 1190 by 139, we get 8 with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 660027.8
If we take 1112 away from 1190, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 10:
The number 139 fits into 780 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 660027.85
Deduct 695 from 780 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 11:
139 goes into 850 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 660027.856
If we subtract 834 from 850, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
If we divide 160 by 139, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 660027.8561
Subtracting 139 from 160 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
If we divide 210 by 139, we get 1 and a remainder of 71.
The next digit of our result is 1. 
Result so far: 660027.85611
Deduct 139 from 210 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

In conclusion, the division gives 660027.85611 with a balance of 7.1e-05.
